Answer:
Axis of symmetry: x = –1; Vertex: (–1, 0); f(x) = –2x2 – 2x – 1
Step-by-step explanation:
What are the vertex and axis of symmetry of the equation?
The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .
Answer:
Hi, there I'll help you since no one helped you which I felt sad lol, but anyway here's your answer
x=2,y=7→ y=11-2x;4x-3y=-13
x=5,y=2→ 2x+y=12;x=9−2y
x=3,y=5→ y=10+x;-3x+3y=30
x=7,y=3→ x+3y=16;2x−y=11
Hope this helps :)
X² + 64 = 0
⇒ x² = -64
But x² can not be negative. So there is no answer
